Specification of Letters Patent.

Patented Feb. 1o, 1914.

Application led April 23, 19'13. Serial No. 783,014.

('0 all vrwhom it 'may concern in the county of Rush and State of Kansas, have invented certain new and useful Improvements in Door- Closures; and I do hereby declare the following to be a'full, clear, and exact description of the invention, such as will enable others. skilled in the art to which it appertains to make and use the same.

An object of this invention is the provision of a device readily applicable to doors for automatically sealing the opening thereunder when the door is closed.

A further object is to provide means for automatically lifting the sealing strip when the door is open so as to leave a clearance between the bottom of the door and the floor.

A further object is to provide a detachable sealing strip and operating means therefor which will automatically adjust themselves to the wear of the threshold.

In the accompanying drawing, Figure 1 represents a fragmental view of the lower portion of a door and frame showing my improved closure applied thereto. Fig. 2 represents a sectional view on the line 2-2 of Fig. 1, and, Fig. 3 represents a sectional view on the line 3-3 of Fig. 1.

Referring to the drawing, the numeral l indicates one side of a door frame, 2 a door hinged thereto and 3 the surface of the floor over which the door operates. The bottom of the door is grooved at 4 and provided with recesses 5 for housing the parts of my improved closure, the base 6 of which is secured against the top ot the groove 4 by screws 7. The groove 4 is preferably terminated short of the free edge of the door so as to provide a protecting strip 8 to prevent dust and dirt from entering the groove 4 and possibly interfering with the operation of the closure device.

The movable sealing strip 9 is preferably formed of rubber or some other material having the equivalent elastic'properties, and is suitably clenched between the turned edges of the metallic strip 10 carrying upwardly extending yoke bolts 11. Spaced openings are formed in the base plate 6, through which project the yokes 11 and threaded Shanks thereof. Springs 13 are interposed between the top of the base plate 6 and the nut. 14 on the end of the stems 12, for nori mally hold-ing the sealing strip' 9 in raised- Be it known that I, Josnrrr YVETSS, acitl- I zen of the United States, resldlng at Brsorn' position.l The tension operating the strip 9 may be increased or diminished by adjustment of the nut 14. It will be understood that the stems 12 are adapted for movement within the openings 5 formed in the top wall of the groove 4.

Ears 15 are struck up from the base plate 6 at intervals thereon and provide bearings for inclined levers 16 having the lower end rounded and engaged against the top surface of the strip 10. The levers 16 are slotted to receive the slide bar 17, which eX- tends through the yoled portion of the yoke bolts 11 and is mounted in the downwardly bent struck out portions 18 of the base 6. The slide bar 17 carries laterally projecting pins 19 engaging within the slots 20 in the inclined levers 16.

As shown in Fig. 1, the levers 16 are in-Y clined from their sides downwardly and toward the hinged side of the door 2. When the door is opened the tension of the spring 13 draws the strip 9 upwardly Within the groove 4 and at the same time projects the slide b'ar 17 beyond the surface of the hinged edge of the door 2. When the door is closed the end of the slide bar 17 engages the abutment 21 and is moved inwardly until the end thereof is Hush with the hinged edge of the door. The pins 19 working in the inclined slots 20 move the levers 16 upon their pivots which engage and depress the clencher strip 10, together with the sealing strip 9, and thus efl'ectually close the opening beneath the door.

The abutment 21 which I employ is usually in the form of a screw, as such a device may be adjusted inwardl and outwardly to increase or decrease t e stroke of the slide bar 17, together with the sealing strip 9.

While I have here shown my invention as inserted in the groove in the under side of a door, I wish it to be clearly understood that I do not necessarily limit myself to this particular mode of attachment, as it is obvious that suitable side pieces may be secured to the base plate 6 for protecting t@ parts of the device and the same applied directly to the bottom of a door.

What I claim is:

A door closure comprising a base plate adapted to be secured to the under edge of av door, a sealing element, yoke bolts secured to said sealing element and projecting upwardly throughsaid base plate, means for resiliently supporting said sealing element upwardly, inclined slotted levers pivoted to said base plate having rounded lower ends resting upon said sealing element, guides carried by said base plate, a slide bar movable longitudinally in said guides, engaging through said yoke bolts, and slotted levers having pins engaged in the slots of the 10 levers.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
